<p>A keytop 1 according to the present invention is used for a push button switch of a mobile phone. A reinforcing fiber layer is formed in an externally-visible state on at least one of a top surface, a back surface or an inner portion of a keytop body made of a resin material. The keytops are manufactured by pressing a laminating material of the sheet-shaped resin member and the sheet-shaped reinforcing fiber layer with a mold and molding the keytop bodies which are attached on the reinforcing fiber layer. By reinforcing the keytop bodies, the thin keytop bodies can be formed. Accordingly, it is possible to easily manufacture the keytops, to reduce production cost of the keytops, and to improve a design of the keytops.</p> |
